Design And Implementation Of A Digital Parks Network System And Network Management

With the rapid development of internet technology,the Internet has become one of the tools that people must use every day.As the applications of the internet grow more and more popular,its' structures and functions are becoming more and more complex.People's life requires a more informatized world,which leads to an urgent demand that we should build a high-quality network system in the modern society.This paper utilized principles of computer network,principles of network design,and various kinds of network security technology to build an efficient and stable network system platform for an industrial park.In this design process,We aimed to use the role of layered network design model to make a detailed division of the internal network,so that it would form the core layer?access layer,and the aggregation layer.Moreover,the design also involved the business Intranet ?the intelligent private network and the office outer network as the core of the network structure that can be deployed and implemented.After a series of actual requirements about the industrial park have been analysis deeply,we decided to adopt the suitable internet device and security products in order to plan the present internet layout.Meanwhile,we used IRF2 technology?QoS program reasonably based on the internet security.During the process of deploying internet security,we put forward some security strategies,such as firewall technology?intrusion prevention system and ACL technology.Otherwise,we offered a design based on SNMP internet management program.Combining with the office demand of the industrial park,firstly we have to reasonable plan IP network?IP address and VLAN of different user department;secondly we have to finish parameter configuration and program deploying of relative internet devices and internet security devices;thirdly we need to rational control each segment of networks by using relative management design.At last,testing the whole network from two aspects—the functionality and the security.The test result indicate that the network and the network security system which we designed and deployed can meet the network communication demand of different office systems in function?bandwidth and handling capacity.Simultaneously,the index of relative network information security has been effectively guaranteed.
